Carboni started his studies in architecture in 1921, but became also interested in graphic and industrial design. His career began at the famous Studio Boggeri, but later he worked on his own. He specialized in exhibitions for trade fairs (Olivetti), interior design and graphics. For many years, Carboni worked for RAI (the Italian radio and TV company), but also for clients who mainly manufactured basic consumer products like Motta (ice cream), Pavesi (bread), Barilla (pasta) and Shell Oil. He presented those clients with a complete graphic line, ranging from packaging to posters. From 1953 to 1960 he worked for Bertolli, for whom he designed a whole series of magazine ads and posters. In 1954 he designed the ‘Delfi no’ (dolphin) chair for Arflex. He wrote several books; Exhibitions and Displays (1959), with an illustrated introduction by Herbert Bayer, features his relatively unknown work from the early 1930s through to the late 1950s.
